To .all whom it mai/. concem:

l Be it known that I, J osEF MALY, a subject 'of the Austro-HungarianEmperor, and residing at Lttichaustrasse '14, Dresden, A.,

Grermany,l have invented certain new and useful Improvements inGas-Producers, of which the following is a specification.

The subject-matter of-the present invention is an improvement ingas-producers and particularly in those in which the-air is suppliedabove a rotating ash-plate which serves compartments, whereby it ispossible to introduce at definite parts of the producer air and steamatvarying pressures, or only air, or more steam than air, or more airthan. steam.v

In order that the invention may beclearly understood reference is madeto the accompanying drawings in which two dierent embodiments arerepresented by way of example and in which Figure l is a verticalsection, and Fig. 2 a plan of one embodiment, whereas Fig. 3 is avertical section, and Fig. 4 a plan of the second embodiment.

In the form represented in Figs. 1 and 2 there is built on the rotatingor revoluble ash-plate a and eccentrically to the same a` cas-ing. bwhich in plan is preferably shaped round, rhomboidal or the like andwhich rotates with the ash-plate. This casing communicates directly witha chamber d under the same accessible from without through a door o. Airis blown into` this chamber through an opening or pipe e. A channel fforming. a water-lock with a ring g projecting downwards from theash-plate prevents the emission of the air below the producer.

As is seen in the drawing the upper part of the casingb isshapedconically-corresponding to the plan of the casing and at b1, .b2like a step-grate. At the one side below i z'the casing b is also shapedconically. The upper part of the cone built on the casing Z formsa-ehamber z' separated from the lower ally.

'pai-t of the casing by a partition h and this chamber z' is providedwith a number of openings c on its periphery. To the chamber z' thereleads a special stationary blastpipe l through which can beintroducedblast of higher or other pressure than into `the chamber d orthe lower part of the casing b.

`The point m of the cone likewise forms a special chamber separated fromthe chamber z' by a partition o and is provided with a special conduitAo which is particularly used for introducing steam of a definitepressure, but which however under certain circumstances can also Abeconnected with a special air-pipe." In the'form represented in Fig. l

of the drawing, the pipe p could serve for p introducing compressed air.In the form represented in Fig. l the chamber z' is thought of asadmitting air miXed with steam, or for air of 'variable pressure,whereas the chamber m is exclusivelyv for admitting steam. From theabove description it i's at once clear that air, or air and steam, oronly vsteam or only air of definite variable pressure or regulatabletension can be introduced optionally at three places or into threedifferent zones of the producer. In the case of many kinds of fuelwhich-lie-very closely or form a compact ash, blastvof high tensionwithout any admixture of steam will be admitted. `In the second zone, orthrough the second chamber z' since purer fuel is situated over the sameand a higher temperature 1sl Several effects ,can be obtained byintroducing steam yat the .point of the conical grate. Firstly it canAbe prevented that the stream of the gases generated above the gratejoins together in tie center and the gases are prevented from burningupwards centric- The steam drives the stream of gases apart and alsocompels the air or mixture of air and steam admitted further below todisi tribute to the sides also and to pass through the whole of thecross-section of the proi ribs'andl the point or cap of the grate orcone is arranged as the drawing shows, somewhatf eccentrically, andconsequently it has a moving or boring action in the center of thelayers ofthe fuel.. The formation of lumps of ashes can also beprevented, an eX- cessive rise of temperature in the center of theproducer being prevented by the decomposition of the excess of steam,andthe eX: cessof heat, which is conducive to the formation of lumps ofslag, is utilized for forming hydrogen by decomposing the steam. It isat once clear that .in the case of such admission of steam andairvariable withinv the ash-plate are pressed'out under 'the wa--ter-level when the ash-plate is rotated and rise to the scraper ordeflector g. and falls over the edge of the plate through Lthe conduitor chute 7'.

The form represented in -Figs. 3 and 4 differs 'from that representedinfFigs.' l and 2 substantially by the chambers z' and n being Iydivided in addition by vertical partitions into compartments a and nand and z", the walls of the compartments being perforated. The chambercompartments n and i have independent pipes, one of these pipes Yconducts to n and the other to 2".,

, steeper than at the other parts of the pe- The principal purpose of`this is to admit more steam at a definite place, namely at the part ofthe conical grate which descends riphery, in order to Abreak upthe'lu'mps of slag more quickly and powerfully, and to utilize the heatstored up vin the same for decomposing the steam. ln the formrepresented in Fig. 3 the'right-hand side of theA producer would workfor forming watergas, and the left" hand side for air-gas. When thegrate is rotatedI these two parts are`gradually displaced of course.Also the arrangement of the ribs s represented in Figs. 3 and 4 is ofgreat importance; these ribs on the conical face of the grate must'contribute much to the uniform working of glass and iron, the lower partof thegrate the generator or to the ashes and slags falling'vdownsimultaneously. As is at once clear, these ribs stir and move theburning layer of fuel, and above all break up the slags. i

For fuels which form slacks as. hard as and also the inner wall of theproducer opposite the grate is provided with ribs in or,-

der to grind the slacks to powder when the grate lrotates in the mannerof a stonebreaker. Since a sandy mass is formed r which in many casesbinds like cement in the water-bath, knife like looseners lare atvducer,with a grate having a rhomboidal chambers, pipes opening into the uppertached at two or more places on theproducer-wall which dips into. thewater-bath, said looseners reaching to the bottom of the dish or plate.When the plate is rotated these knives cut the layer of cement, so thatthe passage for the slacks or ashes below the producer which wouldotherwise be dimin. ished is kept open. l v

What I claim as my invention and desire to secure by Letters Patent isl 1. The combination, in a gas-producer, of a revoluble ash-plate havinga hole in the' same and forming the bottom of the "producer, with agrate having a round or rhomboidal or the like cross-section mountedover said hole eccentrically on said ash-plate, said grate having oneAor more partitions dividing `the same into aplurality of chambers, andpipes opening into said chambers and aording admission thereto of airalone and steam alone, or air and steam mixed.

' 2. The combination, in a gas-producer, o

a revoluble ash-plate having a hole in the same and 4forming the bottom'ofthe procross-section mounted over said hole eccentrically on saidash-plate, said grate having one or more horizontal partitions dividingthe same into aplurality of superposed ,95 chambers and alfordingadmissionv of air and steam and a main blast pipe opening into thelowest chamber and operable independently of said air and steam pipe.

3. The combination, in a gas-producer, of a revoluble ash-plate having ahole in the same and forming the bottom ofthe producer, with a gratehaving a rhomboidal cross-section mounted over said hole eccentricallyon Isaid ash-plate, an annular channel for water under saidA ash-plate,a rin attached to the latter projecting into. sai

channel, said grate having one or more partitions dividing the same intoa plurality of ,superposed compartments, pipes o ening 1.10

into the upper compartments and a Ording admission of air and steam anda main blast pipe opening below said ash-plate into the lowestcompartment.

y 4. The combination, in a gas-producer,` of

a revoluble 'ash-plate having a hole in `the same and forming the bottomof the producer, with a pyramidal grate mounted over said hole in saidash-plate, said grate having a plurality of horizontalv partitions.dividin the same into a plurality of superposed c ambers, a pluralityof pipes opening intol the lower chambers, and a separate pipe openinginto the uppermost chamber in the point of the grate, the point of thegrate 12,5

being situated eccentrically to the axis of rotation of said ash-plate,saidpipes affording independent admission.- of air and steam to'. thetop and ,bottom chambers. 1

5. The combination, in a gas-producer, of

a revoluble ash-plate having a hole in the same and forming the bottomof the producer, with a pyramidal grate mounted over said hole on saidash-plate, said grate having a plurality of horizontal partitionsdividing the same into a plurality of superposed chambers, said gratehaving a perforated vertical partition dividing the upper chambers intocompartments, a plurality of pipes opening into the lower Chambers, anda separate pipe opening into the uppermost chamber in the point of thegrate, the point of the grate being situated ecoentrically to pipesaiording admission of air and steam tothe top chamber independently ofthe supply of air and steam to the'lower chambers and permitting moresteam to be supplied to one side of the upper chambers in said gratethan to the other side.
